It cant be that hard to understand here is the quote the h23 dohc vtec motor exists

"The sporty Accord and Torneo SiR/SiR-T S-packages, the attractively priced newly upgraded Accord and Torneo 2.0VTS 4WD F-type and the sporty Accord Wagon SiR grade, powered by a newly designed 2.3-liter DOHC VTEC engine, are being launched simultaneously from January 21, 1999."

AUTO? i think it comes in stick too. the guy told me that my is a stick. i'm gonna build up the engine before i put it into my 95 accord. i'm gonna sleeve and put pistons and rods in the bloack. i want that engine to take 15 psi. i heard that engine is making 220 hp stock. if i boost 15 psi, then i sould get double the power. 440? that sould like alot too me, but we will see how it goes. i think i should be able to run 15 psi with afc hack. i'm gonna run 550cc injectors instead of 450 cc. if the 450 is good for 12 psi then the 550 should be good for 15 psi. i did the equation and it seem like is gonna work.

In my opinion, the jdm h23 is to much of an engine to be put in a civic.I think you should put it in the accord and go with the sleeper look...

i'm not sure what the spec for the H23a is. i was trying to look for the spec, but i can't find it.

H23A1 has 9.8.1 comp. ratio 160hp@5800 156lb-ft@4500
H22A has 10.0.1 200hp@7000 156lb-ft@5250
H22A1 has 10.0.1 195hp@7000 156lb-ft@5250

the H22A1 in the 99+ prelude has 200hp in the USA (along with the 97+ SIR prelude from japan) but the H22A (97+ prelude type S) from japan has 220hp

i got an h23a (non-vtec) jdm engine in my coupe. it is identical as the h23a1. i will post some pics as soon as i can figure it out. if any one wants i can e-mail. but if u know how to post them into a thread please let me know..

why dont u just slap a h22 head on that h23 u got there vtecwithboost. heard its pretty easy like doing a mini-me. but pushing as much as a type-s motor.

i thought about it but then u got to put the oil squiters and stuff in the block i heard. i am actually looking into an f22 block with the h23 head. but if that doesn't happen i am still gonna boost it! i have seen some preludes turbo's with 245 to 250 with only 6 psi. i am hoping that 10 psi will easily put it over 300!! if not i always will have 10 lbs of nos in the trunk!

that's an oxy-moron... "turbo an h22 and put it in a civic"... I personally don't see why anyone would put an h22 into a civic, but if you did, that would be better suited for an all motor car... you can get the same numbers turboing any motor... Why don't you spend $2-3000 less and build your stock motor or swap a b-series and turbo it. Stock LS's put out about 250hp off of 6-8 psi... why spend $2500+, fuckn up your car's weight ratio/suspension, just so you can say "I have an H22/23 turbo" and get the same performance... going in a straight line, that is

NO WAY.. ITS NOT AS BAD AS U THINK. GRANTED THAT THE CAR WILL LET U KNOW WHEN U AR GOING ALITTLE TO FAST INTO A TURN. BUT GET THE EXTRA 20 TO 30 LBS OF TORQUE OUT OF U UR LS... OR THE 40 MORE IF U GOT THE B16....
plus all the ls and b20 hatches around ain't ---- compared to the h23 i crush them all. i got three friends with ls's and they will tell u everytime i get them by about two car lenghts
plus i only got $1100 into my swap so i figured it was more worth it then putting an ls or b16
